THoNGfcUTTER.

SPECIFICATION forming part of Letters Patent No. 375,372, dated December27, 1887.

Application filed September E, 1887; Sera1No.2^l9.505. (No model.)

.To @ZZ whom t may concern.'

Be it known that I, GEORGE MARSH, a citizen of the United States,residing at Nashville, in the county of Davidson and State of Tennessee,have invented certain new and useful Improvements in Thong.- Cutters;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as. will enable others skilled intheart to which it appertains to make and use the same.

My invention is an improvement in hand cutting-stamps for making leatherthongs or strings; and it consists in certain details of constructionand arrangement ofthe parts composing a vthong-cutting implement whencon-v structed according to my invention, whereby the blade is heldsecure in place or may be removed for sharpening or adj usted to cutwide or narrow strips, as and for the purposes as will be hereinaftermore fully described, and pointed out in the claims.

The objectof my invention is to form a convenient implement orcuttingstamp foruseV of harness-makers, shoe-makers, and others, wherebyleather thongs or stringsv of different lengths and widths may be formedby asingle blow, and to accomplish which I proceed as follows, referencenow being had to the accompanying drawings for a better understanding ofthe details of construction and arrangement of the several partscomposing a thong-cutter when constructed according to my invention,

and in which drawings- Figures l and 2 represent views in elevation of athong-cutter constructed according to my invention; Fig. 3, a centraltransverse sectional elevation of a portion of the lower end of thesame, and Fig. 4. a bottom view. Fig. 5 is a similar view to Fig. 3,showing the clamping-baud as with an inwardly-projecting flange forengaging over the edge of thelast round of the cutter shown in Fig. 6.

A is the handle or body proper of the implement, made of a heavy stoutpiece of wood and with a leather cushion, a, at its top end to receivethe impact of the blow when using the implement and prevent injury totheend thereof, and a central projection, a', at its bot-l tom, upon whichto receive and hold the cutter, as will presently appear. Around thelower end of the handle A is a band, B, for

clamping the cutter-blade in position upon ,the handle.

K is the cutter blade or knife, which is made of a single strip of thinspring-steel-such as a clock-spring-*having one edge sharpened, and witha slot or similar means, as at 7c, receiving astud, ce2, on theprojection a of the handle, whereby the cutter is held in place.

l? is a continuous narrow strip of leather interposed between theconvolutions of the cutterblade to separate said convolutions thedesired distance apart. At the back of the cut-ter a cushion, b, mayalso be arranged to prevent injury to said cutter and handle:

. As before stated, the cutter is a thin strip of springsteel, so thatstrips of leather ofdifferent thicknesses may be interposed between thesame and the distance apart of said convolu tions increased ordiminished, whereby thongs of different width is the result.

When arranging theimplement for use, the cutter is first attached to thecentral projection, a', of the handle. A narrow strip of leather of thedesired thickness the thong is to be is now placed adjacent thecutter-blade and the two cu'rled 0r wound tight around the saidprojection of the handle, and then held secure in place by theclamping-band B, which j band may be slotted with setscrew, as in Fig.

1, or with ears, as in Fig. 2, to facilitate the adjustment thereof. Theinstrument isnow placed upon the piece of leather from which the thongis to be cut, when, upon a sharp blow being directed upon the top end ofthe handle, the outteris forced through the leather and divides the sameinto a narrow strip or thong, as it is called.

By having the cutter detachable,in addition to that of permittingdifferent widths of thongs to be made, the same may be more readilysharpened than were the knife rigid in its handle. To cut long thongs along cutteris to be employed and the number of convolutions thereofproportionally increased. If desired, the outer end of the cutterAblade,sufficient, say, to make about one revolution of the cutter when curledup, may be formed with a narrow portion, as shown in Fig. 6, to engagean iuwardlyprojecting fiange on the band, as shown in Fig. 5.

I am aware that a helical cutting-die is lnot IOO broadly new. but

Zhat I do claim as new and of my invention is as follows, viz:

l. In a thong-cutter, the combination, with the handle formed with acentral projection to receive the first coil olr the cutter-blade, ofsaid thin spring-Steel cutter-bladewound upon said projection of thehandle, continuous strip of leather interposed between the convolntionsof the blade, and a clampingband for holding` the parts together.

2. rlhe combination, in the thong cutter herein described, with a handlehaving a central projection, ofa helical cutter-blade formed of a narrowribbon of spring-steel, with means at its inner end to engage saidprojection of the handle, means for separating the convolutions of thecntter-blade, and means for secur- This, therefore, I do not claim;

2ol ing the whole to the handle.

3. In a thong-cutter, in combination with the handle, helical cutter,and interposed continuous strip of leather, the clamping-band forsecuring the cutter in position.

4. In a thong-cutter, in combination with the handle and helicalcutter-blade formed with a narrow portion at one end, the clamping-bandhaving an inwardly-projectingflange along its lower edge, for thepurposes specified.

5. In a thong-cutter, in combination with the handle formed with acentral projection to receive the cutter -blade and bearing a stud, theknife with slot at one end and a narrow portion at the other, andclamping-band with inwardly-projecting ange at its lower edge.

GEORGE MARSH.
